Abstract

The utility model relates to an auxiliary surgical blade for the treatment of cataract, which is composed of three parts of a blade rod, a blade arm and a blade head. The blade rod is a cylinder, one end of the blade arm is connected with the blade rod by the transition of an included angle Alpha, the other end of the blade arm is connected with the isosceles triangle blade head, blades are arranged on the two sides of the isosceles triangle; the utility model has simple and reasonable structure, small size and convenient operation and usage, which can effectively improve the safety and the reliability of the nucleus chopping operations and reduce the damages to the surrounding tissues of the eye ball, furthermore, the utility model is applicable to the industrial production and can be matched with various specification of nucleus chopping knives for use.

Description

The cataractous assisted surgery cutter of a kind of treatment

This utility model relates to a kind of medical surgical instrument, and refering in particular to is the cataractous assisted surgery cutter of a kind of treatment.

The treatment cataract can adopt ultrasonic emulsification to absorb three kinds of art, big otch enucleation and nucleus chopping techniques.It is to utilize ultrasonic energy that cataractous lens is carried out emulsifying to absorb that ultrasonic emulsification is absorbed art.This surgical apparatus investment is big, surgery cost is high, is that general patient is not acceptant; Simultaneously, because the effect of hyperacoustic energy corneal can cause the corneal endothelium damage, the recovery of influence operation back vision; Big otch extraction method since otch more than 12-14mm, the corrective surgery infectious-related complication is outstanding, tissue injury is big, operation safety is poor, vision restoration is undesirable.At present, mainly adopt three-dimensional maneuver with nucleus chopping technique treatment cataract both at home and abroad, as Japanese cataract expert Momose split nuclear pincers nucleus chopping technique, domestic Yao Ke cuts the nuclear method, all be to adopt three-dimensional maneuver to split the nuclear operation at two faces (front and back of nuclear) of crystal nuclear, because operation is in anterior chamber's operation, the space is little in the room, and operation easier is big, easy damaged cornea and back cyst membrane, operation reliability, safety is lower.

The purpose of this utility model be to overcome the deficiency of prior art and provide a kind of rational in infrastructure, volume is little, the cataractous assisted surgery cutter of treatment easy for operation, that operative incision is little.

This utility model is to adopt following proposal to realize: it is made up of knife bar, tool arm, cutter head three parts.Described knife bar is cylinder, be connected with angle α transition between tool arm one end and the knife bar, the other end of tool arm is connected with an isoceles triangle shape cutter head, on two waists of isosceles triangle, be provided with blade, and α is 120 °～170 °, cutter head isosceles triangle apex angle ss is 20 °～30 °, and isoceles triangle form height H is 1～3mm, and bottom side length L is 0.5～1.2mm.

Concrete structure of the present utility model describes in detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is the utility model axonometric chart;

Accompanying drawing 2 is the A portion amplification plan view of accompanying drawing 1;

Accompanying drawing 3 is the front view of accompanying drawing 2.

See accompanying drawing 1,2,3, this utility model is made up of knife bar 1, tool arm 2, cutter head 3, described knife bar 1 is a cylinder, and be connected with angle α transition with tool arm 2 one ends, cutter head 3 is the other end that an isoceles triangle shape and two waists are provided with blade 4 and are packed in tool arm 2, and angle α is 120 °～170 °, and the isosceles triangle apex angle ss of cutter head 3 is 20 °～30 °, high H is 1～3mm, and bottom side length L is 0.5～1.2mm.

Using method of the present utility model is summarized as follows: split when operation nuclear carrying out cataract, because of knife for nucleus cutting is being split when nuclear, need crystalline lens to be fixed by assistive device, so that split nuclear, therefore, utilize the blade of this utility model cutter head two waist settings directly to insert in the crystalline lens, and the plane that utilizes its isosceles triangle cutter head to constitute makes lens positioning, so that knife for nucleus cutting is split nuclear in crystalline lens, because this utility model volume is minimum, therefore, the edge of a knife is very little, tissue around the difficult damage eyeball can effectively promote reliability and safety that cataract is split the nuclear operation, can examine the supporting use of scalpel with various splitting.

In sum, this utility model is simple and reasonable, and volume is little, easy for operation, can effectively promote safety, the reliability of splitting the nuclear operation, the edge of a knife is little, little to eyeball surrounding tissue damage, be suitable for suitability for industrialized production, can with the supporting use of the knife for nucleus cutting of all size.
